Yeah..some members over on SPCR also found the static pressure to be only ok, better then the S12 that's for sure, but not as good as the 1200rpm S-Flex. The thing is though, the quality of fan/motor noise from these Noctuas is excellent. Better the Scythe in my opinion. As good if not better then the Nexus. And used in cooling an NF-P12 heatisnk as they are intended, they are almost silent at 1300rpm inside a PC case, even with 2 of them in push/pull. (Anand mentioned this iin his review). I've tried S-Flex (all models), SilentX, YateLoons, SilentEagles, Akasa Ambers, Nexus, Acoutifan, and I reckon the Noctuas P12's offer the best balance between cooling and noise. So while there are fans which push more air (and noisier) for the airflow the Noctua P12 pushes and the noise levels it has I think it's the best fan out there.
